We conducted a systematic review of 15 relevant databases for articles about telemedicine. After eliminating articles that did not meet the inclusion criteria, 1615 remained for analysis. Three raters coded the articles to assess various theoretical and methodological variables. Only 5% ( n = 85) of the telemedicine articles made mention of any theory or paradigmatic approach. Studies commonly reported the objectives (96%) but rarely stated a research question or hypothesis (11%). Randomized selection of the subjects was reported in 11% of patient studies and 4% of studies where providers were the subject. There was a wide range in the number of subjects employed, although the majority of studies were based on sample sizes of less than 100. Only 26% of the studies reported a time frame. Until the telemedicine field adheres to agreed standards of reporting methodological details it will be difficult to draw firm conclusions from review studies.

This article addresses the issue of conflict between religious communities that cause enmity amid society. Hostilities must be overcome and resolved in accordance with the call of Christianity to live in love and peace. The study used the qualitative paradigm as the method of the research and the descriptive-analyses as the writing method by describing the research problems based on data collected from related publications.One of the powerful messages of Jesus's teaching is "Love your enemies." It’s one of the greatest challenges in life. Jesus Christ gave an important doctrine about loving the enemy because love is more powerful than evil, hurtful deeds. Loving the enemy means canceling hostilities and violence, but instead, it promises acceptance of each other. The title of this study is "love your enemies": A Christian Response to Embrace Others. As the title of this study is "love your enemies," the reason for the selection of this article is because the author sees that "loving the enemy is a commandment from God that must be obeyed. This research question emphasizes how to realize "loving the enemy" amid hostility. This paper argues that Jesus's command to love the enemy is a proper Christian lifestyle choice in the midst of hostility. We use CS Song thoughts, which elaborated with other scholars' views on theology, loving, and embracing others. The purpose of the research was to gain understanding and build a theological reflection on Jesus' commandment to love the enemy. In this article, we first briefly discuss the portrait of life among religious people in Indonesia. Secondly, we discuss the conflict between religious people in Indonesia. Finally, we apply the command of Jesus to love our enemy as a Christian lifestyle in the midst of hostility to construct harmony amid hostility. We propose the command of Jesus to ‘love your enemy’ as a response to establishing sustainable peace by embrace others. Finally, the Christians must become a loving community because God so loved us, and we also ought to love and embrace others.

AbstractThis systematic review aimed to contribute to a better and more focused understanding of the link between the concept of resilience and psychosocial interventions in the migrant population. The research questions concerned the type of population involved, definition of resilience, methodological choices and which intervention programmes were targeted at migrants. In the 90 articles included, an heterogeneity in defining resilience or not well specified definition resulted. Different migratory experiences were not adequately considered in the selection of participants. Few resilience interventions on migrants were resulted. A lack of procedure’s descriptions that keep in account specific migrants’ life-experiences and efficacy’s measures were highlighted.

Auditory Verbal Therapy

This systematic review sheds light on the effectiveness of auditory–verbal therapy (AVT) outcomes in children with cochlear implants (CIs). The presented outcome is based on research findings from the last 10 years. The systematic review was designed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and Critical Appraisal of Treatment Evidence (CATE) checklist. Specific keywords were chosen based on the research question and searched on the PubMed database. All searched papers were analysed based on specific exclusion criteria and classified into four evidence levels. The results revealed that children who participated in AV therapy can achieve linguistic skills at the same level as their hearing peers. Voice quality seemed positively affected, placing young children with CIs in the normal range for receptive vocabulary development. In contrast, reading skills seemed less benefited. AV therapy seems to contribute to integration into mainstream society. Despite the recorded speech and language improvements of young children with CIs, the aim of AV therapy is still not fulfilled. AV therapy can be seen as the best clinical practice for young children with CIs till now, but the lack of well-controlled studies is undermining.

Blockchain is a technology that can be applied in different sectors to solve various problems. As a complex system, agribusiness presents many possibilities to take advantage of blockchain technology. The main goal of this paper is to identify the purposes for which blockchain has been applied in the agribusiness sector, for which a PRISMA-based systematic review was carried out. The scientific literature corpus was accessed and selected from Elsevier’s Scopus and ISI of Knowledge’s Web of Science (WoS) platforms, using the PRISMA protocol procedures. Seventy-one articles were selected for analysis. Blockchain application in agribusiness is a novel topic, with the first publication dating from 2016. The technological development prevails more than blockchain applications since it has been addressed mainly in the Computer Sciences and Engineering. Blockchain applications for agribusiness management of financial, energy, logistical, environmental, agricultural, livestock, and industrial purposes have been reported in the literature. The findings suggest that blockchain brings many benefits when used in agribusiness supply chains. We concluded that the research on blockchain applications in agribusiness is only at an early stage, as many prototypes are being developed and tested in the laboratory. In the near future, blockchain will be increasingly applied across all economic sectors, including agribusiness, promoting greater reliability and agility in information with a reduced cost. Several gaps for future studies were observed, with significant value for science, industry, and society.

Recent developments in the online distribution and consumption of audio-visual content have brought relevant changes to the transnational flow of content. Thus, the need for a theoretical and methodological rejuvenation of flows research has been signalled. The aim of the present study is to analyse the different flow studies throughout time, following a series of parameters such as research question, methodology and scale of study. This article is a systematic literature review of 30 flow studies on film and television programmes, published between 1974 and 2014. The methods used by the studies are brought into focus and discussed thoroughly, in light of the method of data collection, the type of data used and the method of data analysis. Main findings show an evolution towards more detailed research, to include more contextual factors, an increased use of secondary data, as well as more focused regional and comparative studies.

This paper, responds to the recent calls in research, to address the theoretical underpinnings of entrepreneurial strategies in MNC’s. Today, a multiplicity of entrepreneurial approaches exists, cf. skunk work, bricolage, bootlegging. However, these exists in disparate literature, that provides limited oversight to managers in, that need to select between a manifold of different entrepreneurial strategies. Moreover, these approaches typically originate from a distinctively different organizational context, namely SMEs. Through a literature review we identify two important axiomatic assumptions concerning entrepreneurial strategies within the organizational conditions of MNCs. The first fundamental assumption concerns the organizational origin of such effort. The second theoretical assumption deals with how the entrepreneurial initiative can meet either organizational resistance or support. We synthesize these two dimensions into a two-by-two matrix, that provides an answer to our research question: what are the critical dimensions for entrepreneurial strategies in an MNC context? We then employ this typology to categorize predominant entrepreneurial strategies in current literature, to create a overview that can be used both for structuring the debate in the literature; as well as a basis to discuss important implicit assumptions, that should guide the selection of entrepreneurial strategy in a MNC context in practice.
